Uplink 5500EZ Att LtE model setup by Alarm Relay. Replaced the older 4500ez which got phased out.

I could never get that to work on my M1G. Elk support (at the time) said it was unsupported and they had no plans for an update. Is yours fully working?

Works great.

What's the model number from the unit? All the docs I found for the EZ show empty solder pads where the serial header should be. Would love to get serial comms for LTE!

Will get into attic to get specifics. It had the same serial header as as previous unit. I used the existing serial cable to my Elk.

That's excellent news.
Thanks, I really appreciate the help!

Uplink 5500 AT&T version. Works great with Ek and monitored by Alarm Relay.

Here is the link to 4500 series from one of my post. It is the same pinout for 5500. I will need to get my hands on a 5500.

I'm really glad to hear you've got that working. I've got the same unit sitting on a shelf because I couldn't get it to work with Geoarm. The thing that's really confusing me is that when I was troubleshooting with Elk about my 5500ATT not working, the resolution was this:
 

Our Product Manager was able to get the UpLink 5500 for ELK Engineering to evaluate. The connector on the 5500  has the pinout for Tx, Rx, and Gnd but apparently Uplink is using a different RS232 serial protocol.  The current M1XSP Firmware 10.0.6 to support the UpLink4500EZ is not compatible with the new UpLink 5500 unit.  At this time I can’t guarantee ELK will create an M1XSP Firmware version to support the UpLink 5500. If we do release a version I’ll be glad to let you know.
 
Thank you,

But you've quite clearly got it working! Do you recall doing anything "unusual" when you set it up?

Nothing at all. Just worked on phone with Alarm Relay and Uplink to activate unit and test. Drop in replacement for previous 4500 unit. Same serial header. Same message it outputs if Cellular service drops. Same Elk rules to alert me of Uplink drops service still work from my original Uplink unit.

Alarm did have some issue that they had to consult with Uplink. Had a three way support call at one point then Uplink got Alarm Relay straighten out and it worked.

Alarm relay sold me the 5500 and even asked me to pick a cellular provider that had best service in my area. AT&T has the best coverage in my area.

Para 3.3 about steps to activate unit serial for Elk. Despite the references to the micro USB port no USB connection is used . Same serial cable as previous uplinks units works.

Uplink rep read that section to Alarm relay tech and that got it working.

Exactly the experience I was hoping to have the first time I tried to use it as a drop in replacement for my 4500. I've been looking to change to Alarm Relay anyway and this will be a great reason to do it. I can't thank you enough for your help.

 

[serodgers]

Thank you for providing the serial header pin outs years ago. That allowed me to make my own serial cable instead of purchasing one.

Wow. That was almost 10 yrs ago. I may end up going with a 5500 for Verizon network.
